History of Latvia between 1621 - 1721
During the Polish–Swedish War (1600–1629) Riga and the largest part of Duchy of Livonia came under Swedish rule in 1621. During the Swedish rule Vidzeme was known as the "Swedish Bread Basket" because it supplied the larger part of the Swedish Kingdom with wheat. The rest of Latvia stayed Polish until the second partition of Poland in 1793, when it became Russian.
In 1632 the Swedish king Gustavus Adolphus founded Dorpat University which became the intellectual focus for population of Livonia. The translation of the whole Bible into Latvian in 1685 by Johann Ernst Glück was subsidized by the Swedish government. Also the schools for Latvian speaking peasantry were set up in the country parishes.
Riga was the second largest city in the Swedish Empire at the time. Together with other Baltic Sea dominions, Livonia served to secure the Swedish Dominium maris baltici. In contrast to Swedish Estonia, which had submitted to Swedish rule voluntarily in 1561 and where traditional local laws remained largely untouched, the uniformity policy was applied in Swedish Livonia under Karl XI of Sweden: serfdom was abolished in the estates owned by the Swedish crown, peasants were offered education and military, administrative or ecclesiastical careers, and nobles had to transfer domains to the king in the Great Reduction. These reforms were subsequently reversed by Peter I of Russia when he conquered Livonia.
After the Polish–Swedish War (1600–1629) only the Southeastern part of the Duchy of Livonia ramained under Polish-Lithuanian rule. The Catholicism became the dominant religion in this territory known as Inflanty or Latgale as a result of Counter-Reformation.

Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
